Although signal boosters can improve cell phone coverage, malfunctioning, poorly designed, or improperly installed signal boosters can interfere with wireless networks and cause interference to a range of calls, including emergency and 911 calls.

When properly installed, signal boosters can help consumers, wireless service providers, and public safety first responders by extending cell phone coverage to areas that would otherwise have weak signals such as tunnels, subways, inside buildings, and in rural areas.

Signal boosters are devices that amplify wireless signals to extend coverage.
